i dont think its really about wheather it saw combat or not as much as wheather it was deployd in ww2 that makes it a ww2 usuable plane.
Since it was deployd during ww2, i think it counts as a ww2 aircraft, youll find them in plenty of ww2 books.
Sepcially sence were talkin about MA usable stuff, F8f would actually be used and stand a chance in the MA environment, give it a perk and add it. At least itll be used.
